Doubly-Robust LLM-as-a-Judge: Externally Valid Estimation with Imperfect Personas

Luke Guerdan, Justin Whitehouse, Kimberly Truong +2

As Generative AI (GenAI) systems see growing adoption, a key concern involves the external validity of evaluations, or the extent to which they generalize from lab-based to real-wo…

Validating LLM-as-a-Judge Systems under Rating Indeterminacy

Luke Guerdan, Solon Barocas, Kenneth Holstein +3

The LLM-as-a-judge paradigm, in which a judge LLM system replaces human raters in rating the outputs of other generative AI (GenAI) systems, plays a critical role in scaling and st…

Measurement as Bricolage: Examining How Data Scientists Construct Target Variables for Predictive Modeling Tasks

Luke Guerdan, Devansh Saxena, Stevie Chancellor +2

Data scientists often formulate predictive modeling tasks involving fuzzy, hard-to-define concepts, such as the "authenticity" of student writing or the "healthcare need" of a pati…

A Framework for Evaluating LLMs Under Task Indeterminacy

Luke Guerdan, Hanna Wallach, Solon Barocas +1

Large language model (LLM) evaluations often assume there is a single correct response -- a gold label -- for each item in the evaluation corpus. However, some tasks can be ambiguo…
